'Structurally deficient' bridges across the state

Last update: January 28, 2008 - 2:08 PM

The data in the table below are for bridges in Minnesota that have received comparable or worse inspection ratings as the one that collapsed. A sufficiency score of 80 percent or less means the bridge likely needs some rehabilitation. A rating of 50 percent or less means the bridge may need to be replaced. The bridge that collapsed was rated at 50 percent.

Also included are ratings for the bridge deck, superstructure and substructure. Those ratings are on a 0-9 scale, with 9 being excellent. A rating of 4 is low enough to be considered deficient.

The table only includes bridges that are open to traffic on "mainline" highways that are designated as Interstate Highways, U.S. Numbered Highways, or State Highways. The data is from the National Bridge Inventory database, current as of February 2007.
